TotaZZ whom it may concern.-

Cleveland, in the county oftnyahoga-f and State of Ohio, have invented aeertaiu new and lmprovedMethod of Crushing' and lulveriz-v ing Quartz and Similar Substances, of which the following is 'a full. eletti', andv exactdescri ption, reference beingr had to the accompanyin-g;r drawings of the sante, making par: ot' tltis specitication, of which-- Figures l and'2 represent side elevations of' i my improved machine; ltig. 3, a plan ot' the same. Fig. Irepresents a side elevation of tite machine with one end of the'crushing-cylinder removed to show t hc construction of its t partsyFig. 5, a plan of the intetiir surface of the cylinder, and Fig. ti a moditication of the same.

The'principle of my invention consists tn reducing the quartz or similar material to powlttrial is driven with great speed and force by the beaters, and thcrel'ty reduced to dust or powder.. v

Ott the end li, next the fratne of the machine and through its center, is cata circular opening, through which 'the shaft F passes, while. in the outer-end, l{,.of the cylinder, and at its cellier, is cut another circular opening, but of larger size, for the purpose of feeding the quartz or other material to the machine, to be pulverizcd, for which purpose a hopper of snitable shape and dimensions may be attached to the inachine,"although notrepresented in the drawings. At or near the innerperipher ot' the cylinder cnt through either end, but in this case the inner ettd or disk, K, ofthe casing l, anothei` opening, to which is secured a carryingtube,L,through which is forced the pui-- verizcd quartz or othersubstancc as fast as ground;` and' by it conducted wherever desired. In this instance the arms or beaters, for thepurpose of strength and to lighten as hinchas possible their weight., are represented as being.r cast on a disk, (l, which tapers' from the shaft F outward; but, if desired, they may be cast on a hub', or in any other suitable nian'nerconsisteut with strength; or they may either be* made flat or curved, but .smooth on their facen 4 The shape of the disk on which'they arecastJ To enable others skilled in the artto make, t (when a disk is used) may bo made inV such construet,and use my.improvement, I will 'now fori-n as soonest to bring thc rebounding pieces g ofquartz bach to the action of the arnis'or l beaters again, and by thctn tort-cd' with -gre-a-t. The crushing. or pulvt-tiz'i'ng,Y z-ipparatus may i velocity on thc'tcet-ln yThe. beaters'or arms rnay be made in such forni, whether straight or curved, as may he most conducive to'strcngth and ability to withstand the torce ofthe blow and to act on' the pieces of rock, &c. lWhere t-eetlt'dare formed on the inner periphery' of beaters or arms c ofthe disk will force or throw the'roeks or stones with immense force and ve locity`vv outward tott'ardl the tocthedfcylinder,
